I'm a Senior Fellow at the Cato Institute, a libertarian think tank based in Washington. I also serve as Chairman of the Board for the Center for Freedom and Prosperity, an organization created to defend and promote tax competition. I previously served as a senior fellow at the Heritage Foundation and also was an economist for Senator Bob Packwood and the Senate Finance Committee. I received my Ph.D. in economics from George Mason University and a B.A. and M.A. in economics from the University of Georgia.

Eduardo Saverin, the billionaire co- founder of Facebook Inc. (FB), renounced his U.S. citizenship before an initial public offering that values the social network at as much as $96 billion, a move that may reduce his tax bill. …Saverin’s stake is about 4 percent,
according to the website Who Owns Facebook. At the high end of the IPO valuation, that would be worth about $3.84 billion. …Saverin, 30, joins a growing number of people giving up U.S. citizenship, a move that can trim their tax liabilities in that country. The Brazilian-born resident of Singapore is one of several people who helped Mark Zuckerberg start Facebook in a Harvard University dorm and stand to reap billions of dollars after the world’s largest social network holds its IPO. “Eduardo recently found it more practical to become a resident of Singapore since he plans to live there for an indefinite period of time,” said Tom Goodman, a spokesman for Saverin, in an e-mailed statement. …Singapore doesn’t have a capital gains tax. It does tax income earned in that nation, as well as “certain foreign- sourced income,” according to a government website on tax policies there. …Renouncing your citizenship well in advance of an IPO is “a very smart idea,” from a tax standpoint, said Avi-Yonah. “Once it’s public you can’t fool around with the value.” …Renouncing citizenship is an option chosen by increasing numbers of Americans. A record 1,780 gave up their U.S. passports last year compared with 235 in 2008, according to government records. …“It’s a loss for the U.S. to have many well-educated people who actually have a great deal of affection for America make that choice,” said Richard Weisman, an attorney at Baker & McKenzie in Hong Kong. “The tax cost, complexity and the traps for the unwary are among the considerations.”

What makes this story amusing, from a personal perspective, is that Saverin’s expatriation takes place just a couple of days after my wayward friend Bruce Bartlett wrote a piece for the New York Times, in which he said that people like me are exaggerating the impact of taxes on migration.

In recent years, the number of Americans renouncing their citizenship has increased. …the number of Americans renouncing their citizenship rose to 1,781 in 2011 from 231 in 2008. This led William McGurn of The Wall Street Journal to warn that the tax code is turning American citizens living abroad into “economic lepers.” The sharply rising numbers of Americans renouncing their citizenship “are canaries in the coal mine,” he wrote. The economist Dan Mitchell of the libertarian Cato Institute was more explicit in a 2010 column in Forbes, “Rich Americans Voting With Their Feet to Escape Obama Tax Oppression.” …the sharp rise in Americans renouncing their citizenship since 2008 is less pronounced than it appears if one looks at the full range of data available since 1997, when it first was collected. As one can see in the chart, the highest number of Americans renouncing their citizenship came in 1997. …The reality is that taxes are just one factor among many that determine where people choose to live. Factors including climate, proximity to those in similar businesses and the availability of amenities like the arts and cuisine play a much larger role. That’s why places like New York and California are still magnets for the wealthy despite high taxes. And although a few Americans may renounce their citizenship to avoid American taxes, it is obvious that many, many more people continually seek American residency and citizenship.

I actually agree with Bruce. Taxes are just one factor when people make decisions on where to live, work, save, and invest.
